Oracle looked good in Race 8 on Saturday with Jimmy Spithill sailing well to windward. Analyzers say the “learning curve” on the 72-foot boats is still dramatic and day-to-day. Hints that Oracle also made changes to daggerboards. Got to give Dean Barker credit for saving Emirates from this near capsize. Race 9 called because of too much wind. I know the Cup competition often is all about rules, but I still can’t get over the Oracle penalty for adding 5 pounds of ballast — if I i understand it correctly — to one of the 45-foot trainers. But it’s almost worth it just to see these boats come around a mark on foils and fly downwind.
